Answer: A
Step-by-step explanation:
Since multiplication is the only operation under the radical, you can apply the root to each term. Im not sure if I worded that correctly, but ill hopefully explain correctly.
First we need to take the cubed root of 648. This number doesn't have a perfect root, but it can be simplified. 648 is the same as 216*3, and 216 has a perfect cubed root of 6. So we can bring the 6 outside of the radical
[tex]3x*6\sqrt[3]{3x^4y^8}=18x\sqrt[3]{3x^4y^8}[/tex]
The next step is simplifying the variables, which is the easiest part. Just split them up into multiples of 3, again poor explanation but Ill show what I mean.
[tex]18x\sqrt[3]{3x^3xy^3y^3y^2}[/tex]
The cubed root and the cubed power will cancel and can be brought outside the radical[tex]18x*xy^2\sqrt[3]{2xy^2} =18x^2y^2\sqrt[3]{3xy^2}[/tex]

A computer and printer cost a total of $900. The cost of the computer is three times the cost of the printer. Find the cost of each item.
Answers
C = computer cost
P + C = 900
C = 3P
P + 3P = 900
4P = 900
P = $225
C = 3(225)
C = $675
A truck covers a distance of 16 km in 30 minutes.
How much distance can it cover in 5 hours while
travelling at the same speed?
Answers
Given:
A loaded truck covered 16 km in 25 minutes.
To find :
How far it can travel in 5 hours?
Solution :
Converting hours to minutes -1 hour = 60 minutes5 hours = 5 x 60 = 300 minutes5 hours = 300 minutes.
Finding the distance covered by truck in 5 hours -In 25 minutes it covered 16 km.
300 minutes = ?
km= 300 x 16 ÷ 25
=4800 ÷ 25
= 192
Answer:
260 km for 300 mins
Step-by-step explanation:
16 km in 30 mins (half an hour)
There are 300 minutes in 5 hours
16 km for 30 mins
32 km for 60 mins
48 km for 90 mins
64 km for 120 mins
80 km for 150 mins
96 km for 180 mins
112 km for 210 mins
128 km for 240 mins
144 km for 270 mins
160 km for 300 mins
( all you need to do is keep on adding 16 km and 30 mins until you get to 5 hours/300 mins)
So the truck covers a distance of 260 km for 300 mins

Raul came home with $3.00 in his pocket. He had given Rene $1.50 on his way home. Pedro gave him $1.00 that he had borrowed last week. How much money did Raul have at the beginning of the day?
Answers
Answer: $3.50
Step-by-step explanation:
He came home with $3.00.
He gave Rene $1.50 which means that $1.50 was deducted from his money.
Pedro gave him $1.00 which added to his money.
Money he had therefore was:
= 3 + 1.50 - 1
= $3.50

there were 1125 cell phone users in 2000.
С
the rate of decay is 3.4%

Answers
Answer: B
there were 1125 cell phone users in 2000.
Step-by-step explanation:
The initial number of cell phone users is the front coefficient that is then multiplied by the growth factor.
So the initial number of cell phone users in 2000 was 1125.

Answer:
$25,689.775
Step-by-step explanation:
The interest has to be in decimal form. So 1.25/100=0.0125
Plug everything into the equation for compound equation [tex]A=P(1+\frac{r}{t})^{n}^{t}[/tex]
Which is A = 24750 [(1 + 0.0125/1)^(1)(3)]
Type them in a calculator and get A ≈ $25,689.775
***the question says "compounded annually" so the equation for compound interest [tex]A=P(1+\frac{r}{t})^{n}^{t}[/tex] should be used. Your provided formula of A = P(1 + R times T) shouldn't be used here, it is for simple interest but not compound.*** (^_^)

second. Let's suppose they start to walk to each other when
t=0. How many seconds will it take for the students to bump
into one another? Give your answer to the nearest whole
number.
Answers
Answer: 20
Step-by-step explanation:
first you make it into a equation
then you have to make both sides equal the same thing by doing that you figure what t is and t will be your answer
100=2(t)+3(t)
100=2(20)+3(20)
100=40+60
100=100
t=20
It will take 20 seconds for the students to bump into one another.
What is a system of equations?A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Student A, has a speed of 2 meters each second;
Student B, has a speed of 3 meters each second.
Let's suppose they start to walk to each other when t=0.
first we will make it into a equation then we have to make both sides equal the same thing by doing that you figure what t is and t will be your answer.
100=2(t)+3(t)
100=2(20)+3(20)
100=40+60
100=100
t=20
Therefore, it will take 20 seconds for the students to bump into one another.

What is the minimum value for the function shown in the graph?
Answers
Answer:
2.5
The lowest point on the graph, or the minimum is at f(x)= 2.5
The minimum value of the given periodic function is, 2.5
What are functions?Function is a relation between a set of inputs and a set of outputs which are permissible. In a function, for particular values of x we will get only a single image in y. It is denoted by f(x).
Vertical line test:-
Whenever we want to check whether a given expression is a function or not we can apply a vertical line test, in this test we check for a single image of x , we are getting a single image or more.
If we get more images then it will not be a function.
For example, let us take, y² = 4ax
y = ±√4ax
For single value of x we get two values of y
Hence, it will not be a function.
Given that,
A periodic function,
Period = 3π
The value of the function is in the range of (2.5, 4.5)
So,
Maximum value = 4.5
Minimum value = 2.5
Thus, the minimum value is 2.5
